You could put a strip of clear acetate in-between the icing and the rope/twine. Clear acetate can be purchased in craft stores or chocolate/candy sections of cake decorating stores.
ask her if she would want to eat french fries or sandwiches tied with (unsanitary) rope -- rope as you know is so easily made from fondant -- I wouldn't make/serve that to anyone -- it's worse than risky -- the bride is asking you to be irresponsible -- just say no is what I would do --
rope can easily be incorporating into the reception in any number of ways -- there's no reason for it to on the food
best to you
and y'know what your bride would probably say yes she would eat the fries tied with dirty rope -- it's her choice -- but the greater point is that she should answer "no" to serving that to anyone else especially her loved ones and so should you
Lol - love the answer
I am still looking for acetate right now, but if I can not find it, I am going to see if cellophane is strong enough. I also was told by someone to maybe use a satin ribbon that is the same color as the cake. So I am going to try these things and see if it works out. Thanx for your suggestions!
to answer your original question no there is no way to make rope food safe -- to continue is to take great risk with stranger's health
my rule of thumb is if i would do this to the baby's porridge, or grandma's mashed potatoes then i would do it for the guests at xyz wedding -- bottom line it is unsafe and you bear the burden of providing safe food -- best to you -- decision's yours
there are many other ways to incorporate rope into the design and retain your integrity
@K8memphis you are totally right, but as she said her bottom two tiers were fake, so those two tiers can accommodate the rope/twine (as they will not be consumed).
@aluvs2bake - the loose fibres from the rope/twine will still be a issue (might get air-born), so you could spray thoroughly with clear lacquer or hairspray or olive oil before attaching to the bottom 2 tiers of the cake.
ohhhhh gooood -- i should have gone back and re-read that -- phew so happy!
Confectioner's Glaze comes in an aerosol albeit it's a bit pricey (around $30). It does last a long time and you can spray it on the rope to prevent loose fibers from falling. A lot easier than painting on clear lacquer. It will dry hard to the touch.
